Even-71m' ANDREW J. PREscoTT, or. cATAWIssA, PENNSYLVANIA.

Letters Patent No. 107,196, dated September 6, 1870.

To all whom it may concern:

Be it known that I, ANDREW J.Pnnsoor1, of Gatawissa, in the county of Columbia and in the State' of Pennsylvania, have invented certain new and usefnl Improvements in Car-Coupling;'and do I lereby declare the following isga full, clearand exactdescription thereof', reference being had to the accompal l ying drawing and to theletters oi' reference marked thereon making a part'of this specilieation( The nature oi`.my invention consists in the construction'and arrangement oifa car-coupling, which is so arranged that cars of au unequal height can be couple.l with thesame ease as those oi' the same'height.

In l order tol enable others skilled in the art to which my invention appertains to make and use the s une, I, will. now proceed to describe its construction and operation, referring to the annexed drawing, in whivh- Figurel is a side view,

Figure 2, a plan view, and

Figure 3, a horizontal section of a 'draw-head or bumper, with my improved coupling.

A represents thev draw-bar, and

B, the head or bumper, which extends la suitable distance below the draw-bar, as shown in fig. 1.

On each side of lheentrance, within the head B, is

'placed an upright bar, C, turning on pivots at its ends,

and surrounded hy a spiral spring, -D, the lower end of'which is inserted in the bottom of' the head, as shown in iig. l, while the upper end bears against an arm, b, vexteinling from the upper pivot, a, of thebar,

immediately below the top of the head.

The bars C C, with their springs D D and' arms b b, are vso arranged that, when no coupling-link or piu is inthe head B, the arms b b will beimmediately under the hole in the top of the head through which -the coupling-pin E is to pass, and hence form a rest The coupling-link Gr is constructed in f the usual manner. Y

foi-'said pin.

ltv should be here remarked that the lower pivots of' the hars C O are inserted and tit nicely in holes made for the'ln in the bottom oi' the bead, while the upper pivots a a are placed in elongated slots in the top oi' the head, as shown in iig. 2.-

Wheu the coupling-link G is inserted, it not only presses the bars C C, or rather the upper ends of said bars, outward, but also turns them inward. on their pivots, thereby removing` the arms b b from under -the coupling-pin E, which then falls down and couples they cars.

I n so inserting the coupling-link the springs D D act as guides for the link, preventing,lr it from turning,

and, a-t the same time, the construction of the head admits oi', coupling cars of' unequal height. It does not matter-where the link enters, whether high up or low down, it acts in'precisely the same manner upon the bars O C. As soon as the pin E is raised up and the link withdrawn, the springs D D, pressing upon the arms b b, at once turn the bars G 0,50 that`- the Y l said arms will come under the coupling-pin, and form the rest for the same,. as above-described.

The springs D D also-act to hold the coupling-link wherever it may be inserted, the coils of said springs dividing the height oi' the head into sp tees of about the same width as the thickness of the link. The bottom har ot' the drawbar A passes through the head B at or about its center, and may he raised orl lowered slightly at the entrance tothe head, the sides of said entrance being slotted for that purpose.

The object of this is that, in case the coupling-link should strike immediately above or belowsaid' bar, the-springs would be drawn ont oi' shape, unless this bar yielded sufficient to allow the link to pass.

The upper pivots a ot' the bars G C' work in slots in the head, so that, when the link is inserted, the uplper ends ot' said bars will separate slightly, thereby allowing the arms b b to pass each other, which they could not do if' the bars C O remained at the same distance apart. A

Having thus fnllydescribed my invention,

\Vhat 1 claim as new, and desire to secure b y Letters Patent, is

1`. The bottom bar of the draw-har extendingv through the center of the head, and working up and down in' slots on the same, substantially as and i'orthe purposes herein set forth.

2. '.lhe combination -ot' the. 'bars O C with arms. b b and springs D D, constructed and arrangedv as described, Within the draw-head B, and operating substantially as and for the .purposes herein set. forth.

-In testimony that I claim the foregoing, I have hereunto s et my hand this 22d day of July, .1870.
